"Is there something wrong with the materials?"
Hearing this, Claire immediately pulled himself out of his dilemma and asked back while looking at the Dragon Country students not far away.
"Yes, there is a problem with the material." Xu Kai nodded and continued, "In my opinion, there is no problem with your workmanship."
"The reason why the airbag can't be inflated is simply because there is too much material in the airbag."
"My advice is that you should remove two more layers."
"But after removing two layers, the entire airbag is completely exposed to the lining, which not only has the possibility of damage, but also affects the appearance."
"You know how hard it is to find an airbag that is the same color as the lining and looks like it's one piece."
Hearing this, Claire shook his head without comment and prepared to continue studying the improvement plan.
But just as he lowered his head, Xu Kai spoke again:
"Now that you can't even use the most basic things smoothly, why should you care about aesthetics?"
"Are you making this thing for use or for beauty?"
After these words came out, Claire paused for a moment.
He found that he seemed to have really reached a dead end.
yes...
The things you make yourself are mainly for use. Is appearance really that important?
"But it's not impossible to combine the beauty and practicality you mentioned."
"How to combine?!" Hearing this, Claire's eyes lit up, and he walked to Xu Kai in three or two steps, staring at him with burning eyes.
Although he still doesn't know the origin of this Dragon man.
But I don't think there will be any problems with the people Lowry brought.
And the other party seems to be really capable?
He put all his efforts into this surfing suit, so it would be great if it could be improved now.
"Didn't you just mention the safety of exposed airbags?"
"This can indeed be combined with aesthetics, but the design of your surfing suit may have to be completely redesigned."
"The design of your current surfing suit is too slim, and the airbag is located completely close to your chest. If the material is not up to standard, it will indeed cause unnecessary danger."
"And for the sake of aesthetics, the inflation valve of the airbag is set too small. Under the pressure of the ocean and the limitations of the materials, it is indeed difficult to inflate it."
"So to solve this problem, I suggest you change the position of the airbag."
"Change position?" Claire hesitated for a moment after hearing this: "Where can we change to?"
"From a scientific point of view, the buoyancy device located on the chest is the most effective. All the big-name life jackets are designed in this way."
"You also said that it was a life jacket."
"But what you're making now is surfing suits, which is a completely different concept, okay?"
After asking his mistress to translate Claire's words for him, Xu Kai answered again in English with difficulty.
He found that his English level seemed to have reached its limit.
After the first few sentences, it became increasingly difficult for him to communicate with the other party.
The vocabulary is too small.
Seeing Xu Kai's conflicted look, Zhang Ting fortunately once again acted as an interpreter for the two of them.
"So where do you think is suitable?" Claire asked.
"The abdomen." Xu Kai answered seriously: "The abdomen is not only located in the same position on the body, but also has a much larger space than the chest. After all, the abdomen does not have hard bones."
"But can the abdomen really allow a person to float up perfectly?" Claire still seemed a little hesitant at this time.
He even measured his abdomen, with a hint of confusion in his eyes.
This thing is a portable inflatable bag, not a swimming ring, and it doesn’t have that much space.
Can the buoyancy of the abdomen alone really keep someone safe when they fall into the sea?
Claire couldn't believe it.
Seeing this, Xu Kai was too lazy to talk nonsense and directly asked Lowry for paper and pen, then found a place and started his drawing work.
After a short while, Xu Kai drew a simple diagram of the human body.
Although I can't paint the picture according to my own feelings like Zheng Chen.
But as the deputy chief designer of Class 9.
Xu Kai is now very familiar with the structure drawing of some objects that can be seen everywhere.
After finishing the drawing, Xu Kai immediately started to do calculations on it.
The buoyancy required for the standard weight of a human body is calculated to that produced by carbon dioxide.
From these two buoyancy calculations, the required toughness of the airbag material can be calculated.
To this end, he also assumed a number of variables.
Finally, an answer was obtained:
"You see, from an ergonomic point of view, the inflatable bag at the waist can also play the same buoyancy role and will not cause deviation in the human body."
"Although the effect may be a little worse, these can be corrected through materials."
“This way, we can solve the problem of limited space.”
"Moreover, we can make air bags with different buoyancy according to different body shapes. As long as you choose the air bag that best suits your weight, you can completely get rid of the drawbacks of your current surfing suit."
Looking at the densely packed drawings and formulas in front of me, listening to Zhang Ting's instant translation.
Claire's mind was full of question marks.
He pointed at the picture and then at Xu Kai, and took a long time to say a word.
Finally, he could only look at Lowry and said blankly:
"Laurie, are you sure we're not dreaming right now?"
Hearing this, Lowry raised his eyebrows, took a few steps to Claire's side, raised his right leg and kicked him.
